Which method is recommended for protecting sensitive data on a physical server?

• A. Using RAID for redundancy
• B. Encrypting data in transit
• C. Regular software updates
• D. Implementing user access controls

Answer: (A)

Using RAID for redundancy primarily focuses on providing data availability and fault tolerance rather than protecting sensitive data directly. RAID (Redundant Array of Independent Disks) is a technology that combines multiple hard drives into a single unit to safeguard against data loss due to hardware failure. While it is an important aspect of server management, it does not address the security of sensitive data from unauthorized access or breaches. The recommended method for protecting sensitive data specifically involves encryption. Encrypting data ensures that even if unauthorized individuals gain access to the physical server or its storage devices, they cannot read the information without the appropriate decryption keys. This protection is vital for safeguarding sensitive information, such as personally identifiable information (PII) and financial data. Considering the other methods mentioned, while regular software updates are essential for maintaining security by patching vulnerabilities, and implementing user access controls is crucial for limiting unauthorized access, neither directly protects the data itself in the way encryption does. Data in transit protection is also important, but it primarily addresses data security while being transferred over networks rather than on a physical server. Thus, the best approach for protecting sensitive data on a physical server is through encryption, which ensures that the data remains secure and unreadable to anyone without the necessary access permissions.
